を得られるものである〔請求項（１）］。<Function> In other words, the seal bar to which the ribbon-shaped heater is attached descends toward the seal receiving pad in order to heat and seal the packaging film, and the entire sealing surface and the seal receiving surface metal of the seal receiving band are heated and sealed. The entire sealed portion of the film is pressed between the pad and the surface, but at that time, the protruding stripes on the seal receiving pad deform due to their rubber-like elasticity, so they do not interfere with heating and sealing of the sealed portion. Furthermore, the corresponding portion of the film is partially pinched with a much larger pinching force than other planar portions. Therefore, the sealed portion is completely heated and sealed, and more heat from the ribbon heater is transmitted to the region corresponding to the protrusion, so that the necessary melting temperature can be easily reached, and the film is melted there. In other words, the sealed portion is completely sealed, and the unsealed portion is separated from the sealed portion with a portion of the sealed portion attached, resulting in a complete top seal. Furthermore, since the protruding stripes are formed integrally with the seal receiving pad, they are completely unaffected by temperature changes, and the above-mentioned perfect top seal can always be obtained under the same conditions.

〈実 施 例〉
以下、この発明の実施例を第１図〜第５図を参照して説
明する。<Example> Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 5.
このシール受けパッド１は、ゴム状の弾性を有する素材

一部に切欠き５が形成されている。The seal receiving pad 1 is made of a material having rubber-like elasticity, specifically silicone rubber, and is shaped like an elongated square rod to correspond to the ribbon-shaped heater 2. The seal receiving surface 3 is integrally formed with a protrusion 4 that extends longitudinally through the seal receiving surface 3. The cross section of this protruding strip 4 is Δ-shaped, and a notch 5 is formed in a part thereof.

ール面６ａ全面とシール受けパッドのシール受け面３全
面との間でフィルム７．７のシール部全体が挟圧される
状態にまで下降させ、その状態でリボン状ヒータ２に通
電する。When impulse sealing is performed using this seal receiving pad l, as shown in FIGS. 2 and 3, the sealer 6 to which the ribbon-shaped heater 2 is attached is connected to the entire sealing surface 6a and the seal receiving pad. The film 7.7 is lowered to a state where the entire seal portion of the film 7.7 is pressed between the entire surface of the seal receiving surface 3, and in this state, the ribbon-shaped heater 2 is energized.

付けてままの包装品は、未シール部９の回収処理手段が
設けられた次ぎの工程においてこの未シール部９を分離
・回収され、完全なトップシールのシール部８を持つ包
装品となる。At this time, the protruding stripes 4 of the seal receiving pad 1 are deformed by their rubber-like elasticity, so that they do not interfere with the heating and sealing of the sealing part 8, and moreover, they have a much larger clamping force than other flat parts. The corresponding portion of the film 7.7 is partially compressed. Therefore, the seal portion 8 is completely heated and sealed, and more heat from the ribbon-shaped heater 2 is transmitted to the portion corresponding to the protrusion, so that the necessary fusing temperature can be easily reached, and the film 7.7 , except for the part corresponding to the notch 5, and is fused there. Then, the packaged product with the unsealed part 9 slightly connected to the sealed part 8 by the part corresponding to the notch 5 is processed in the next process in which a means for collecting the unsealed part 9 is provided. The seal portion 9 is separated and collected, resulting in a packaged product having the seal portion 8 with a complete top seal.
つまり、シール部８については完全なシールがなされる
と共に、未シール部９はシール部８の一部を付けたまま
シール部８より切り離されることになり、完全なトップ
シールを得られることになる。In other words, the sealed portion 8 is completely sealed, and the unsealed portion 9 is separated from the sealed portion 8 with a portion of the sealed portion 8 still attached, resulting in a complete top seal. .
ここで、このシール受けパッド１の特に秀れた点は、凸
条４がシール受けパッド１自体に一体的で形成されてい

条件で前述した完全なトップシールを得られるという点
である。尚、凸条の横断面をΔ状とすることは、より秀
れた溶断性が得られるという点で好ましいが、必ずしも
これに限られるものではない。Here, the particularly excellent point of this seal receiving pad 1 is that the protruding stripes 4 are formed integrally with the seal receiving pad 1 itself, so it is not affected by temperature changes at all and is always kept under the same conditions as described above. The point is that a complete top seal can be obtained. It is preferable that the cross section of the protruding stripes be in the shape of Δ, since this provides better fusing performance, but the present invention is not necessarily limited to this.
第４図及び第５図に示される例は、いずれも凸条を波形
に形成した例で、第４図のものは鋭角的な波形の凸条１
０の例、第５図のものは鈍角的な波形の凸条１１の例で
ある。このように凸条を波形にすると、開封を容易にす
るための波形溶断線をシールと同時に形成できるという
利点がある。The examples shown in FIGS. 4 and 5 are examples in which the protrusions are formed in a wave shape, and the example shown in FIG.
0, the one shown in FIG. 5 is an example of a protrusion 11 having an obtuse waveform. When the protrusions are formed into a wave shape in this manner, there is an advantage that a wave-shaped fusing line for facilitating opening can be formed at the same time as the seal.

線をシールと同時に形成できるものである。<Effects of the Invention> As explained above, the seal receiving pad according to the present invention is made of a rubber-like elastic material, and the seal receiving surface facing the ribbon heater is made of fir. Since the cutting ridges are integrally formed, sealing and fusing can be performed perfectly, and the ridges used to fuse and separate the unsealed part from the sealed part are completely unaffected by temperature changes. It is possible to perform a complete top seal under the same conditions at all times, and by making the cross section of the protruding strips into a delta shape, the pinching pressure at the protruding stripes becomes acute, resulting in better fusing performance. In addition, a part of the protrusion is cut out so that the part corresponding to the cutout remains as an unfused part, so it is easier to collect the unsealed part that should be cut away, and the protrusion is made into a corrugated shape. By bending the seal, a wave-shaped fusing line can be formed at the same time as the seal to facilitate opening.
